I haven't worked with Stockcharts. If you need to print screen, you can just press PrintScreen (or PrtScr) button (provided, you're using a PC), and then paste it into any application that can handle graphics, from MS Paint to Word, to Photoshop.
The usuals, whatever I post is my opinion, yaddayaddayadda. I'm still learning this, so if you listen to me, well, good luck to you :)
